The goddess Gyronna is also known as The Angry Hag, and for good reason. She is not a popular deity as many fear her and her clergy, which is entirely female These are usually the throwaways of society: disfigured prostitutes, wives caught in adultery, pregnant teenagers disowned by their parents, and so forth. Priestesses are renowned for their ability to foster hatred and turn friend against friend. Her priestesses are also known to swap young babies for hideous monstrous creatures birthed from their own womb.[1]

The priesthood itself has no canon or book of scripture, or temples; instead, they favor small shrines of simple piled stones. Some of these piles have stones of cats-eye, from which (it is rumored) the hags of Gyronna peer.[2]

The Black Sisters of Gyronna are blamed for causing the downfall of Heibarr, in the River Kingdoms. The ruins of the town are now a site of pilgrimage for some priestesses. [3]
